title: Defective specialized SP beta transducing bacteriophages of Bacillus subtilis that carry the sup-3 or sup-44 gene.
abstract: We isolated defective specialized transducing phages of SP beta that carry one of the extracistronic suppressors, sup-3 or sup-44. Lysates containing these phages can be used in a simple spot test to determine whether an auxotrophic mutation can be suppressed. The sup-3 and sup-44 mutations are distinct, in that their suppression patterns differ for the markers hisA1, metC3, and thr-5; and they are not alleles.
